Kensington’s Transforming PowerLift Back-Up Battery

Unless they’re built into a sleeve, most backup batteries designed for the iPhone and iPod Touch are monstrous affairs that really take the portability out of your handheld gadgets. But Kensington’s new PowerLift, a 1,200 mAh lithium-ion polymer backup battery, embraces its size and bulkiness, transforming into a sturdy dock with a built-in connector that also happens to grant your device 20 more hours of music playback, 5 more hours of video, 3.5 more hours of talk and even an extra hour and a half of FaceTime.

It’s even got a built-in USB cable so it’s completely self-contained when you’re away from home, and a set of LEDs lets you know how much juice it’s still got left. $49.99, currently available for pre-order from Kensington.
